andycowuk 0 Posted June 2, 2011 I haven't looked recently, but I do recall asking about this before when checking continuity on each of the lines - so I think its normal... Quote Share this post Link to post Share on other sites
Supercharged 2 Posted June 2, 2011 I think it's something to do with the reference for the purple signal wire... On most G60's I've seen the 4 pin lambda plug only connects to a loomk with 3 wires - this is becuase the earth wire connects to a bracket ontop of the rear engine mount.

dannyboy 0 Posted June 2, 2011 Not 100% sure but i think that wire is used as a diagnostic feed to the ecu.Tells the ecu if the lamba sensor is busted Quote Share this post Link to post Share on other sites
